Negative calorie foods are a myth, according to nutritionist Louise Dunford.
There is no evidence to support the claim that celery, grapefruit, broccoli, tomatoes, and cucumber have negative calories.
Even the lowest calorie foods contain more calories than it takes to break down and absorb them in the body.
Replacing high calorie foods, like chips and burgers, with lower calorie foods, like fruits and vegetables, can help lower calorie intake and lead to weight-loss. 

Diets are everywhere, but could eating “negative calorie” foods, such as celery and grapefruit, help to boost weight loss?

calorie is a unit of energy, usually expressed as kilocalories (kcal) for the energy content in food. The theory behind negative calorie foods is that some foods have lower calorie (energy) content than the amount of energy it takes to digest and absorb the food into the body. This sounds plausible, in theory. But in reality, even the lowest calorie foods, such as celery, contain more calories than it takes to break down and absorb them in the body.See the rest of the story at Business Insider
